WINDOW.

Application filed July 6, 1926.

My invention relates t-o windows for use in building structures such as ollices, factories and` dwellings.

It is an object of the invention to provide a window, the sashes ot' which are reversible to expose the outer side inwardly for washing. It is also desired that the sash be quickly removable from thecasing.

It is a further object to construct ythe sash and iframe so that the windows are removable without danger of dropping or injury tothe window or to the user.

lt is also desired to term a window with a sash removable and so formed as to be weather tight to prevent entrance ol wind or rain. l

Referring to the drawings herewith, Fig. 1 shows a Side view of a window, the frame being in vertical section, the sash being partly in elevation and partly in vertical s ec tion. Fig. 2 is a broken elevation of the Joint of the upper sash. Fig. 8 is a side view of the upper end of the casing and the upper and lower sash. Fig. `4 is a transverse seetion on the line 4 4 ot Fig. 1. Fig. 5 is a broken detail of one ot the riders. Fig. G a de ail illustrating the attachment of the sasn cord. Fig. 7 is a detail ot the sash plate; and Fig. 8 a broken detail in perspective oit the window jamb between the` two sashes. Like numerals or reference are applied to like parts in all the views.

The invention disclosed herein is an 1mprovcment upon the dev ice set out in my prior application copcndmg herewith, filed June 10th, 1926, as Serial No. 115,141. The lower sash 1 and upper sash 2 are mounted in the usual position'within a window casing including a lower sill having a stool 3, an in clined ledge 4, jambs 5, and head plate G. To the outer side ot the casing is a head board 7, within which is a cross piece 8 grooved on its lower side to receive a stop plate 9 for the upper sash.

Thelower sash lis provided at its sides with riders 10, which are detachably conneeted with said sash. Said riders comprise bars of the same length as the lower sash and having attached thereto at their upper ends a sash cord 11.

As shown in Fig. 6 the sash cord is fitted within a groove in the outer face of the rider, and the lower end ot the cord is extended through an opening 12 in the rider. The

Serial No. 120,599.

cord is further secured in position by transverse screws 13 extending through the rider The sash cords extend overA upper end, in the manner shown in Fig. 5.

The lower sash is iormed with upper and lower pins 19 and 29,V respectively, said pins projecting beyond the sash and into rthe grooves 17 and 15, respectively, in the riders.

lVhen the lower sash is to be raised, it is raised with the rider, eachV rider moving withinfa slideway 21 in the window jamb 5. Toward the upper end of said slide-way is a stop member 22, the lower end ot'` which acts to limit the upward movement of the rider. Tt' it is desired to remove or reverse the lower sash, said sash is elevated slightly in the rider, as shown indotted lines in Fig. 3. This brings the pin 19 out of the groove 17 ofthe rider and allows the upper end of the sash to be swung inwardly about the lower pin 2O as a pivot, and it is contemplatedthat the sash will be lowered to bring said pin to the lower end of Vthe slot 15. The sash may be then swung downwardly until the upper end contact-s with the window stool 3. This will malte it possible to wash the outer side of the window pane. i .f l

lt' it isdesired to remove the sash, the `pin 2O will be moved upwardly inthe slot 15 and out through the opening 16, thus releasing Itv will be obvio-us that the sash may be again insertedfin position by re- `versing the operation described.

The upper sash 2 is not adapted' to slide in the casing. It has at its lower end a supporting plate 23 at each` side. y This plate is Set into the side of thelsash and screwed yinto position by wood screws 24. Said .plate v'has' side of the bracket is formed a lateral arcuate flange 28. As shown in F ig. 8, the window jamb 5 is formed with a curved recess 29 therein to the rear of the slideway 21 of the lower sash. rlhe said recess is cut on the are of a circle so as to allow the movement therein of the lower end of the upper sash and of the lateral flange 28 thereon.

Then it is desired to move the upper sash, the lower sash is left in position. The ripper end of the sash 2 is then pulled inwardly, the sash swinging on the pivot formed by the pins 19. ln so swinging it to be noted that the flange 28 of the plate 23 will bear against the surface 25) formed in the jamb. There will, therefore, be no lost Vmotion at the joint when the sash is swung inwardly, as clearly noted from Fig. 2. When the sash has been moved inwardly until the sash has passed the horizontal position, the flange 28 will move out of the recess 29, but when this occurs the weight of the window will be forwardly, tending to hold the plate in contact with the pin 19. If the sash is to be removed thereafter, this may be accomplished by lifting the sash tofree it from the pins 19 in an 0lovi-V ous manner. rlhe sash may again be inserted in position by a reversal of this operation.

l contemplate making the window weatherproof by placing upon the sides of the jamb adjacent the sash, strips 30 of metal, the inner edge of which is recurved and adapted to fit within a groove 31 in the upper sash when said sash is in closed position. A similar strip 32 is adapted to lit within a similar groove, indicated at 38 in Fig. l, in the lower sash.

It is also to be noted that the flange 18 upon the rider 10 closes the space between the rider and the sash on its forward side so that no space is provided for the entrance of rain or wind.

he improvements made in the shape and the general construction of the rider makes the lower sash easily'operated and weatherproof. The mounting at the lower end of the upper sash prevents accidental release of fallingr` of the sash while it is being opened.

It is believed that the advantages of the construction will be apparent without further description.

lhat I claim as new and desire to protect by Letters Patentis:

1. A window including a casing, a lower sash, laterally projecting pins thereon, an upper sash, plates at the lower end of said upper sash removably engaging said pins, said upper sash being adapted to swing on said pins, and means on said plates co-operating with said casing to hold said plates on said 2. A window including a easing, a lower sash, laterally projecting pins thereon, an upper sash, plates at the lower end of said upper sash removably engaging said pins, said upper sash being adapted to swing on said pins, and means on said plates co-operating with said casing to hold said plates on said pins, while said sash is swung to a horizontal position, said means comprising an arcuate flange on each plate.

A window including a casing, a lower sash, laterally projecting pins thereon, au upper sash, plates at the lower end of said upper sash removably ei'igaging said pins, said upper sash being adapted to swing on said pins, and means on said plates co-opera ting with said casing to hold said plates on said pins, while said sash is swung to a hori- Zontal position, said means comprising an arcuate fiange on each plate, said i'lange eX- tending downwardly and laterally from the lower edge of said plate to lit within a recess in said casing.

el. ln a window, a casing, upper sash and lower sash therein, said lower sash having laterally extending pins at its upper and lower ends, riders for said lowersash having grooves at each end to receive said pins, plates at the lower end of said upper sash, brackets on said plates engaging the pins at the upper end of said lower sash and adapted to pivot thereon, there being a vertical recess between said lower sash and its said rider to receive said bracket, said recess being closed on the forward side, in the manner described, and means on said bracket co-acting with said casing to hold it in engagement with said pins when said sash is swung inwardly.

5. A window including a casing, a lower sash, an upper sash, plates at the lower end oil said upper sash, and projecting `forwardly therefrom, said plates having slots therein. pins adapted to be received in said slots and furnish pivots for said upper sash, and means on said plates engaging with said Vcasing to hold said plates on said pins. l

6. A window including a casing, a lower .sash` an upper sash, plates at the lower end of said upper sash. and m'ojectingforwardly therefrom, said plates having slots therein, pins adapted to be received in said slots and furnish pivots lor said upper sash, and means on said plates extending laterally therefrom perpendicul-arly to the planes of said plates, to hold said plates on said pins.
